5KP36A-G Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP36A-G is an active Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This unidirectional Zener-type TVS diode features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 86.06A peak pulse current capability in a through-hole R-6 axial package. The part is ROHS3 compliant and rated for operating temperatures from -55°C to 150°C.

Equivalent and substitute parts are necessary when the original 5KP36A-G becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when higher power dissipation or current handling capabilities are needed for specific circuit protection requirements.

Substitute Part Grouping Explanation

Substitution of the 5KP36A-G is determined by the following critical electrical and mechanical parameters:

Voltage Parameters: Reverse standoff voltage must be 36V (±tolerance), breakdown voltage minimum 40V, and clamping voltage maximum 58.1V to maintain equivalent circuit protection characteristics.

Current and Power Ratings: Peak pulse current and power dissipation capacity determine the part's ability to suppress transient events. Substitutes with equal or higher ratings are functionally compatible.

Package and Mounting: Through-hole axial packages (R-6, P600, DO-201, DO-15) are mechanically interchangeable in PCB designs, though lead spacing and physical dimensions vary.

Temperature Rating: Operating temperature range must support the application environment. The 5KP36A-G operates to 150°C; substitutes rated to 175°C provide extended thermal margin.

Compliance and Status: All substitute parts must maintain ROHS3 compliance and active product status for production use.

Engineering Selection Recommendations

Direct Electrical Equivalents (Same Voltage and Power Rating):

The A5KP36A-G (Comchip Technology, Cut Tape packaging) and 5KP36A-TP (Micro Commercial Co, Cut Tape packaging) are direct electrical equivalents to the 5KP36A-G. Both maintain identical 36V reverse standoff, 40V breakdown minimum, 58.1V clamping voltage, and 5000W peak power dissipation. The A5KP36A-G differs only in packaging format (Cut Tape vs. Tape & Box), while the 5KP36A-TP offers extended temperature rating to 175°C. Both parts are ROHS3 compliant and active products.

The 5KP36A-E3/54 (Vishay General Semiconductor, TransZorb® series) provides electrical equivalence with identical voltage and power specifications but uses a P600 package instead of R-6. This part is suitable for applications where P600 package compatibility is required and offers extended temperature rating to 175°C.

Higher Power Capacity Substitutes (36V Voltage Class):

The 15KPA36A (MDE Semiconductor Inc) and 30KPA36A series (MDE Semiconductor Inc and Littelfuse Inc, 30KPA36A-B) provide 36V voltage class protection with significantly higher peak pulse current and power dissipation ratings (15kW and 30kW respectively). These parts use P600 packages and are suitable for applications requiring enhanced transient suppression capability while maintaining the same voltage protection threshold. Both manufacturers' parts are ROHS3 compliant and active products.

Lower Power Capacity Substitutes (Reduced Rating):

The 1.5KE36A (Taiwan Semiconductor Corporation) and P6KE36A (Fairchild Semiconductor) operate at reduced voltage standoff (30.8V) with significantly lower peak pulse current and power ratings (1500W and 600W respectively). These parts are suitable only for applications with lower transient energy requirements and should not be used as direct replacements for the 5KP36A-G in circuits designed for 36V protection.

Compliance and Availability:

All substitute parts listed maintain ROHS3 compliance and active product status. Selection should prioritize parts with confirmed inventory availability and established supply chain qualification within your organization.

Frequently Asked Questions (FAQ)

Q: Can the A5KP36A-G replace the 5KP36A-G directly?

A: Yes. The A5KP36A-G is electrically identical to the 5KP36A-G, with the same voltage ratings (36V standoff, 40V breakdown, 58.1V clamp) and power dissipation (5000W). The only difference is packaging format: A5KP36A-G is supplied in Cut Tape while 5KP36A-G is supplied in Tape & Box. Both are through-hole R-6 axial packages and are mechanically compatible on PCBs.

Q: What is the difference between R-6 and P600 packages?

A: R-6 and P600 are both through-hole axial packages for TVS diodes but differ in physical dimensions and lead spacing. R-6 is a smaller package, while P600 is larger and typically used for higher power dissipation applications. They are not mechanically interchangeable on PCBs without layout modification, though they serve the same functional purpose.

Q: Can I use the 1.5KE36A or P6KE36A as substitutes?

A: These parts have lower voltage standoff ratings (30.8V vs. 36V) and significantly reduced power handling (1500W and 600W vs. 5000W). They are not suitable as direct replacements for the 5KP36A-G in circuits designed for 36V protection. Use only if your application specifically requires lower voltage protection and reduced transient energy handling.

Q: Are the 15KPA36A and 30KPA36A suitable replacements?

A: Yes, for applications requiring enhanced transient suppression. These parts maintain the same 36V voltage class but provide 15kW and 30kW peak power dissipation respectively, compared to 5kW for the 5KP36A-G. They use P600 packages and are suitable when higher transient energy absorption is required. Verify PCB layout compatibility with the larger P600 package.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts listed are ROHS3 compliant and maintain active product status. Verify specific compliance requirements (REACH, ECCN, HTSUS codes) with your supply chain for your application's regulatory requirements.

Q: What temperature range should I consider when selecting a substitute?

A: The 5KP36A-G operates from -55°C to 150°C. Most substitute parts extend this to -175°C, providing additional thermal margin. Select based on your application's actual operating temperature requirements. Extended temperature rating does not affect electrical performance within the 5KP36A-G's original temperature range.
